I agree 99% with you but, you know, BTC - BC its a powerful tool, and as a tool, it is not good or bad, its a tool. If someone with moral/ethic uses it its OK, if someone no so responsible uses it, maybe there is a problem.
I am not in the club of "Lets regulate everything" but im not too in the club of "Let it be" because I don't trust in people as much as maybe some others do. But, i tell you what, ¿Could you imagine a descentralized regulation made by consensus of all BTC users? Maybe its a beginning, we need a regulation to protect ourselves of fraud and so on, but a regulation also that make us more free and more confident in this disrupting technology.
